UDP在本地主机上的可靠性

问题描述

我知道UDP本质上是不可靠的，但是当连接到localhost时，我希望内核以不同的方式处理连接，因为一切都可以在内部处理.因此，在这种特殊情况下，UDP是否被认为是可靠的协议，或者如果缓冲区溢出，内核是否仍会垃圾某些数据包?

I know that UDP is inherently unreliable, but when connecting to localhost I would expect the kernel handles the connection differently since everything can be handled internally. So in this special case, is UDP considered a reliable protocol, or will the kernel still potentially junk some packets if buffers are overrun?

推荐答案

我重复.为了保持可移植性，请始终预期您的UDP套接字可能会丢弃数据包或接收乱序数据.

I repeat a previous answer to a related question. To remain portable always anticipate your UDP sockets might drop packets or receive out of order data.
